Recently installed a 1262N AP in autonomous mode. Have both 2.4 and 5Ghz radios running- Both on separate SSID and VLAN. I think I have 5Ghz channels using 40Mhz bands (bonded) but when I do iperf throughput test I only get about 25Mb throughput. I am sitting within 10 feet of the AP. When I switch to 2.4 I get around 60Mb and that's not bonded. I have tried multiple interfaces on my client side laptop I'm testing with since I thought maybe it was a quirky card or driver but I get same results. Am I doing something wrong here? My laptop shows a 300Mb connection to 5Ghz and 144Mb on 2.4Ghz but I know that's not true thorughput so that's why I was testing this to see what I was really getting and now I'm confused.
Thanks!

Stupid question from me: Do you have all SIX antennas attached? If you do, please specify what models you are are using.

Yes 3 2.2 Dbi 2.4Ghz antennas and 3 3.5 Dbi 5Ghz ones. Part Numbers. AIR-ANT2422DW and AIR-ANT5135DW.

Ok, on the autonomous WAP, run the command "sh dot11 ass
Back to the WAP, please run the following command:
dot11 dot111 carrier busy
dot11 dot110 carrier busy
Do the "sh log" and please post the output or result.

OK commands are a little off but I think I got what you asked for. Highlighted is the laptop I'm on.
